I was going to write an article awhile ago about this not so well known application. It provided simple, selectable, and scheduled backups to your MobileMe iDisk. But with the upcoming iCloud, which sounds great and no longer a paid service, makes the MobileMe Backup version 3.2 obsolete. Maybe it’ll be updated so simple computer maintenance of additional backups can take place.
If you’re still interested in utilizing the MobileMe Backup you can grab it from Apple’s website here.
